Audio/Visual Information Dissemination System

ABSTRACT

Systems and methods for providing information to the public by way of publicly accessible devices. A network of video displays are deployed at publicly accessible locations such as inside public transportation vehicles or at public transportation stations. The video feed to these video displays are provided by a video distribution hub which receives the video feed from a network hub. Different audio feeds are accessible to end users or by telephone. End users can call a telephone interface which receives and routes audio feeds from an audio distribution hub. End users can access audio feeds which may be synchronized with a video feed to provide a complete audio visual experience to the end user. For more useful content, the video displayed at any location may be adjusted to be relevant to the area where the video display is deployed. Audio content synchronized to one of these disparate video feeds can be accessed by the end user by dialing different options through the telephone interface. Audio feeds not tied to a specific video feed, such as radio stations or themed audio feeds, may also be accessed by the end user through the telephone interface.

FIELD OF THE INVENTION

The present invention relates to information dissemination systems andis particularly applicable but is not limited to systems and methods fordistributing information to the general public at publicly accessiblelocations.

BACKGROUND OF THE INVENTION

The reason communications revolution has increased the amount of dataavailable to the public. The public's hunger for more and moreinformation has been whetted by this excess of information.

Current systems for information dissemination, especially fordisseminating to the members of the public who take public means oftransportation, are currently inadequate. These systems are solelyvisual and static. Sandwich boards, billboards, and other very oldstatic forms of advertising are used for such ends. However, as notedabove, these systems are Inadequate. Such static forms are purely visualand cannot be readily changed in response to changed conditions.Unfortunately, the ubiquity of televisions and computers have had adeleterious effect on the attention span of the average person. As such,current static systems are unable to keep people's attention.

Another major drawback of current systems is the lack of an audiocomponent. Again, the proliferation of multi-media devices and theubiquity of multi-media in today's society has the public clamouring forthe same presentation type in almost all of their information input.While there are some information dissemination systems that integrate anaudio portion (such as publicly accessible television sets), these canbe intrusive and annoying to those who do not wish to take advantage ofthe system.

There is therefore a need for an information dissemination system thatintegrates both video and audio components while simultaneously avoidingbecoming an annoyance to those not wishing to access the informationbeing disseminated. Such an information dissemination system should alsobe dynamic in that modifying the information content should berelatively simple. Furthermore, the system should be able to keep endusers (i.e. the public, especially those who are travelling in publictransportation vehicles) occupied and should be able to hold theirattention. Finally, it is also very desirable if such a system would becost effective and financially self sustaining. It is therefore anobject of the present invention to mitigate if not overcome thedeficiencies of the prior art.

SUMMARY OF THE INVENTION

The present invention relates to systems and methods for providinginformation to the public by way of publicly accessible devices. Anetwork of video displays are deployed at publicly accessible locationssuch as inside public transportation vehicles or at publictransportation stations. The video feed to these video displays areprovided by a video distribution hub which receives the video feed froma network hub. Different audio feeds are accessible to end users or bytelephone. End users can call a telephone interface which receives androutes audio feeds from an audio distribution hub. End users can accessaudio feeds which may be synchronized with a video feed to provide acomplete audio visual experience to the end user. For more usefulcontent, the video displayed at any location may be adjusted to berelevant to the area where the video display is deployed. Audio contentsynchronized to one of these disparate video feeds can be accessed bythe end user by dialing different options through the telephoneinterface. Audio feeds not tied to a specific video feed, such as radiostations or themed audio feeds, may also be accessed by the end userthrough the telephone interface.

BRIEF DESCRIPTION OF THE DRAWINGS

A better understanding of the invention will be obtained by consideringthe detailed description below, with reference to the following drawingsin which:

FIG. 1 is a block diagram of a system for distributing informationaccording to one aspect of the invention;

FIG. 2 is a block diagram of an example setup for a video display screenfor use with the system of FIG. 1; and

FIG. 3 is a block diagram of another example set up for a video displayscreen for use with the system of FIG. 1.

DETAILED DESCRIPTION

Referring to FIG. 1, a block diagram of a system for distributinginformation is illustrated. The system has 10 has a network hub 20,multiple video distribution hubs 30A-30E, audio distribution hubs 40A,40B, and at least one telephone interface 50. The network hub receivesmultiple audio feeds 60, video feeds 70, and hub end combinedaudio/video feeds 80 from a variety of sources. These feeds are thenseparated into dedicated audio only and video-only feeds. The dedicatedaudio-only feeds are sent to the audio distribution hubs 40A, 40B whilethe dedicated video-only feeds are sent to the video distribution hubs30A-30E. At the video distribution hubs, the relevant video only feedsare transmitted to multiple video display screens 90A-90K bytransmitters 100A-100E. On the audio side, the telephone interface 50receives the dedicated audio only feed and routes this to the telephoneinterface 50. The telephone interface 50 receives telephone calls fromend users who wish to access one of the audio feeds. The end users, whocould be calling and using their mobile or cellular telephones, canselect one of the available audio feeds. Based on the end user input,the interface 50 selects the relevant audio feed and routes this feed tothe relevant end user.

The network hub 20 can be seen as an audio/video feed aggregator—itreceives feeds from a variety of sources and collects and combines thesefeeds into two signals, a dedicated audio feed and a dedicated videofeed. The sources from which the feeds originate may be legion—the feedscould come from the Internet, a cable TV provider, broadcast TV,broadcast radio, a dedicated video or audio signal specifically createdfor the system, or any other source. The network hub 20 separates thefeeds depending on the content—video feeds are separated and routeddifferently from audio feeds using well-known methods and techniques.Video feeds are aggregated into a first single signal with differentvideo feeds occupying different parts or frequencies of that firstsingle signal. Audio feeds are aggregated into a second single signalwith different audio feeds occupying different parts or frequencies ofthat second single signal. The video feed signal (the first singlesignal) is then transmitted to the video distribution hubs 30A-30E. Theaudio feed signal (the second single signal) is transmitted to the audiodistribution hubs 40A, 40B.

Regarding the video distribution hubs 30A-30E, each one can “tune” intoor isolate one of the video fees aggregated into the video feed signalfrom the network hub 20. The video feed that a distribution hub tunesinto is then passed to a corresponding transmitter. A transmitter thentransmits the video feed to multiple video display screens. Each videodistribution hub 30A-30E can be a video tuner which tunes to a specificvideo feed in the video feed signal. Such tuners are well-known in theart.

The transmitters 100A-100E may be, depending on the implementation,wireless, wired, or optical transmitters. The transmitters 100A-100Etransmit the isolated or tuned into video feed to the different videodisplay screens. Each video transmission hub and transmitter combinationservices video display screens located at a specific geographic area.Thus, one geographic area may have display screens 90A, 90B, 90C,showing video feed A as tuned to by video transmission hub 30A whileanother geographic area may have display screens 90G, 90H showing videofeed B as tuned to by video transmission hub 30D. Such an arrangementallows area—or region—centric video feeds to be distributed to theproper areas. Such an arrangement also allows the system to quicklychange what is being shown in the video display screen in a specificarea. As an example, if an important bulletin alert occurs and is in avideo Q, all of the video distribution hubs 30A-30E could automaticallyswitch to video feed Q, ensuring quick dissemination of the bulletinalert to the video display screens serviced by video transmission hubs30A-30E. Similarly, if the video feed to be sent to a specificgeographic area is to be changed, then only the transmission hub whichservices that specific geographic area needs to have any changes made.That transmission hub may merely need to tune into a different videofeed.

It should be noted that, to assist the viewing public in determining thecontent of the video feed being shown on the display screens, each videofeed can be provided with closed captioning. This way, viewers can readthe text of the audio for the video feed. It should further be notedthat advertising and other relevant data may be inserted into each ofthe video feeds. This may be done by dividing the visual representationof the video feed into separate areas, with each area being providedwith different data. As an example, FIG. 2 illustrates one possibleconfiguration of the visual representation. Area 200 may have the actualmoving video being presented (such as a newscast, a situation comedy, ora soap opera program). Area 210 may present the weather forecast for thecity, area 220 may present a stock market report and area 230 maypresent sports scores. Area 240 may be reserved for the closedcaptioning for the video in area 200 and area 250 may be provided foradvertisements that are targeted to the end users. As noted above, thevideo portions of the presentation (presented in area 200) may bedifferent for different areas. Similarly, different advertisements maybe presented for different geographic areas. Ideally, up to ¾ of thedisplay screen may be devoted to advertising space. Devoting such a highproportion of the screen to revenue generating advertising shouldproduce enough revenue for the operation of the system.

Referring to FIG. 3, an alternative arrangement fro the visualrepresentational is illustrated. As can be seen, the main area of thescreen is divided into multiple areas 200A, 200B, 200C, 200D. Each areamay be dedicated to a different network video feed so that end users mayhave their choice of which program to view. Each video feed has its ownaudio feed which may be accessed by an end user as will be explainedbelow.

Regarding the video display screens 90A-90K, these display screens areideally deployed at publicly viewable areas. These may be deployedinside public transportation vehicles such as subway cars and buses andthey may be deployed as static installations in subway/bus stations,busy street corners, and other areas of populace concentration. Plasmadisplay screens may be used as the display screens and, in oneembodiment, such screens may be hardened and configured to withstand theelements for an outside deployment. Such a deployment may be placedoutside moving vehicles such as buses, thereby providing informationdissemination to not only commuters inside the vehicle but commutersoutside the vehicle as well. For such mobile deployments, wirelesstechnology may be used to transmit the video feed to the video displayscreens. For static deployments, wired technology such as cable,optical, and other well-known technologies, may be used for thetransmission of the video feed to the video display screens. Otherstatic deployments such as inside public transportation vehicles may useflat computer monitors to minimize deployment costs.

To avoid end user confusion due to the multiplicity of programs on asingle screen as shown in FIG. 3 static deployments insidetransportation stations (e.g. train stations, bus stations, subwaystations) and inside transportation vehicles may use multiple displayscreens with specific screens being dedicated to specific network videofeeds. As an example, a single subway car may have 10 screens with 3screens being assigned to show a specific news channel video feed, (e.g.CNN), 4 screens being assigned to show a specific other broadcastnetwork (e.g. NBC), and the rest being dedicated to show a youthoriented channel (e.g. MTV). The division of the number of screensdedicated to specific types of programming can be determined by thesystem operator with a view towards the possible viewers given the timeof day. As an example, when students are likely to be the viewers, morescreens would be dedicated to youth oriented programming.

To further lower deployment costs, manufacturers of the display screenscould offer preferential pricing for their screens to those deployingand operating the system. Such a measure would provide the manufacturersfree advertising as the public would be exposed to their product forfree.

The audio portion of the system 10 operates in a similar manner with oneimportant difference—end users can select which audio feed to access. Asnoted above, the audio feed signal is received by the audio transmissionhubs 40A, 40B. The different audio feeds can be accessed by tuning intoor isolating the relevant audio feed from the rest of the audio feedsignal. This is what the telephone interface 50 does, along withautomatically receiving end user telephone calls and automaticallyrouting the relevant audio feed to the relevant end user telephone call.The telephone interface 50 has multiple tuners with each tuner isolatingor tuning into one of the audio feeds in the audio feed signal. Upon arequest by an end user who is calling in, the relevant audio feed isdiverted or routed to this end user.

The telephone interface 50 acts as an access point for end users. Endusers can call into the telephone interface (with the relevant telephonenumber perhaps flashed on the video display screens) and access aspecific audio feed. To present a complete audio visual experience inconjunction with that with what is being presented on the video displayscreens, at least one of the audio feeds could be synchronized with thepresentation on the video display screens. As an example, if geographicarea A is showing video show A1 on screens 9OA-9OC and geographic area Bis showing video show A2 on screens 901-90K, end users in area A wouldneed to access the audio feed synchronized the video show A1 while endusers in the area B would need to access the audio feed synchronized tothe video show A2. This may be done by-an end user calling the telephoneinterface 50 and, after navigating an automated answering and menusystem, accessing the relevant audio feed. This answering and menusystem is well-known technology and is readily available. Thus, an enduser in area A would, to get the proper audio visual experience, accessa different audio feed from that accessed by an end user in area B. Asyet another variant, the audio feed synchronized to a specific videoshow could be presented in different languages as separate audio feeds.As an example, video show A1 showing on screens 90A-90C could besynchronized to three different audio feeds—one audio feed being inEnglish, another audio feed being in French, and a third audio feedbeing in Chinese. As such, an end user could access any one of the videofeeds synchronized to that specific video show in the language ofpreference for the end user. Thus, a single video feed being presentedin a specific geographic area could be accessible to people who do notnecessarily speak the exact same language. Similarly, the closedcaptioning presented on the video display screens could be presented inmultiple languages or, if one language is predominant in a specificarea, the closed captioning could be presented in that single language.The technology for routing audio feeds synchronized to a video feed iscurrently available and used in passenger aircraft that providesin-flight entertainment. Adapting such technology with appropriatetelephone menu technology will produce the requisite telephone interfacedescribed above.

It should be noted that the audio feeds available need not all besynchronized to the video feeds. Other audio feeds, such as audio feedsthat provide music, commentary, radio station feeds, and others, may beavailable, depending on the implementation. This system is ideallysuited to be accessed by commuters with cellular or mobile phones 260.Commuters, while on their morning or afternoon commute may view thevideo display screens inside the public transportation vehicle or in thestations while waiting for the vehicles. In concert with this, thecommuters can use their mobile telephones to call the telephoneinterface and listen in on the audio portion of the program beingpresented in area 200 of the video display screen. Alternatively, thecommuter may decide not to view the video program on the video displayscreen but merely listen to some other audio program being presented asa separate audio feed through his or her mobile telephone. However, thesystem need not be limited to mobile telephones, End users who have,ideally, a landline speaker phone may also access the telephoneinterface to listen to the different available audio feeds at work or athome. To address the different tastes of different types of peoplesthemed audio feeds, such as all-sports, all-classical music, all-news orall-music (with different audio feeds for different types of music) mayalso be available. As an alternative, end users equipped with mobiletelephones may receive the different audio feeds using Bluetooth orWi-Fi (IEEE 802.11) technology.

To accommodate the different regions in a large geographic area,multiple telephone interface/audio transmission hubs may be implemented,with different telephone interfaces serving different areas.

To allow for a financially self-sustaining system, advertising space maybe sold on either the video feeds (as explained above) or in the audiofeeds. Advertisements may be sold on a per display screen basis, aregional coverage basis, or on a visibility (time visible on screen)basis. Similarly, subscription fees may be collected from end users whowish to access the audio feed. Alternatively, the system could be freeto mobile telephone users with the operational and deployment costsbeing borne by advertisers and/or public transportation bodies.

The system described above is flexible enough for many different typesof advertising and promotions. As an example, advertisers could includein their advertising a specific telephone code which users may enterwhile listening to an audio feed. Entering the code would thenautomatically connect the end user to the advertisers telephone call-incenter so the end user can then take advantage of the offer (e.g. avacation trip for a low promotional price). Alternatively, end users mayestablish an account, with their credit cards on file, with theoperators of the system. These end users may then do their shopping overthe telephone based on what is being advertised on the display screens.End user choices, such as the colour, size, or type of merchandise,could be entered by the end user via the telephone keypad using specifictelephone codes shown in the video feeds. To verify an end usersidentity, PIN (personal identification numbers) could be associated witheach end user account. Such PIN numbers would be required tovalidate/finalize the transaction before the end users credit card ischarged and before the item is shipped to the end users on-file addressor before the end user can pick up the item. As an alternative, an endusers bank account can be tied in with the end users system account andthe purchase price of the end-users purchase can be automaticallydebited to from his/her bank account. The use of PIN numbers or somesimilar scheme for validation for this configuration would, of course,be required for security. End users can also be provided, by of way oftheir mobile telephone's screen, with different payment options. Adedicated PAY button on the mobile handset can be provided so thatactivation of this button brings up the end users payment option.

The system also offers a myriad of advantages to society and the publicin general. It may be used as part of a public broadcasting system toinform the populace of alerts or emergencies. It can also increaseliteracy as those without mobile phones will need to read the closedcaptioning and/or the text on-screen to determine what is beingpresented. It will also produce greater usage of public transportationvehicles as passengers are not only transported from one place toanother but are also entertained. Such an increase in ridership may alsoaugur an decrease in the number of vehicles on the road, thereby leadingto a more environment-friendly society. The increased advertising mayalso lead to greater consumer spending, thereby fueling economic growthfor the areas where the system is deployed.

Although various exemplary embodiments of the invention have beendisclosed, it should be apparent to those skilled in the art thatvarious changes and modifications can be made which will achieve some ofthe advantages of the invention without departing from the true scope ofthe invention.
